Local Swedish media wrote Friday that Sweden has issued advice to local authorities urging them to prepare their civil defense infrastructure and procedures "in terms of war" amid growing concerns about Russia aggression.

The move is believed to be part of the country's return to the Cold War era "Total Defence Strategy", announced last year in response to the "worsening international situation" and "increased uncertainty in the immediate area", the Independent said.

“What is new is that the security situation in our region has deteriorated and that therefore we must prepare ourselves in terms of war and of conflict," Magnus Dyberg-Ek of the the "Totalförsvarsplaneringen" Total Defence Strategy, told Swedish newspaper Svenska Dagbladet (SvD).

“We have sent out the letter in part because local authorities want clear instructions so that they know how to act in a crisis situation.”

He added: “This strategy is not new – we used it during the Cold War and will now strengthen coordination regarding civil defence."

"There is nothing to suggest that war is likely, but we have been given an order from the government to plan for it,” Svante Werger, the press officer for MSB, told the Sydsvenskan newspaper.
